Check the load circuits for those specific regulators, may have something
causing increase current demand.

M # Z35X21D, rebuilt PWM power supply:
Replaced CX3416 100uf, CX 3413 22uf,
CX3424 2200 uf, both regulators, unit works
fine in every way, but regulator heatsink get very
hot. Touch it for 3-4 seconds...ouch. But the unit
runs all day, just afraid it will overheat & "blow"
again. Did I miss anything to cause overheating?
Horizontal output is cool enough. Rono.
